Program Participation and Labor-Supply Response
构建并估计了西雅图和丹佛收入维持实验中的项目参与模型，解释家庭选择接受负所得税、留在实验但不领取或退出实验的原因，并基于参与结果估计了劳动力供给模型。
In this paper, a model of participation in the Seattle and Denver Income Maintenance Experiments (SIME/DIME) is developed and estimated. The model explains why a family chooses to receive negative income tax (NIT) payments, chooses to remain in the experiment but not receive payments, or chooses to leave the experiment (attrition). It is assumed that an individual selects the option that yields the greatest amount of utility. The empirical formulation of the model relates program participation to experimentally induced changes in wage rates, nonwage income, and disposable income, and several nonexperimental variables. Based on the participation results, a model of labor supply with varying participation rates is specified and estimated.
